Library and physics buildings of the TU Wien

We are the Institute of Applied Physics of TU Wien. Most parts of the institute are located in the physics and mathematics building of the TU Wien, the Freihaus. The Freihaus is the light green building in the photo, behind the TU Wien library (with the huge owl at the corner) when seen from Karlplatz.

Our office can be reached weekdays from 8 am - 4 pm. Our address is:

Wiedner Hauptstraße 8-10/E134
1040 Vienna

How To Get There

Karlsplatz is the largest subway station in Vienna. Two subway lines (U1, U4), four streetcars (1,2,62, 71), three bus lines (2A, 4A, 59A) and the Badener Bahn stop here. 

Leave the subway station at the exit "Wiedner Hauptstraße". On Wiedner Hauptstraße, the first building you pass is the TU library (with a huge stone bird on the corner); our institute is in the green physics and mathematics building behind it ("Freihaus", a huge green building; see photo). Take the elevators in "Tower C" (red) to the 5th floor, where you will find the secretariat of our institute (turn right twice after leaving the elevator and ring the bell at the entrance door).

The Biophysics group is located a few hundred meters further west, at Lehargasse 6. You can get there in five minutes from Karlsplatz.

Vienna International Airport (VIE) is located in Schwechat, about 20 km southeast of Vienna city center.

Three rail lines serve Vienna's city center:

  • The best and cheapest way to get there is by Railjet (RJ), which goes to Wien Hauptbahnhof/Hbf. From there, take the U1 subway in the direction of Leopoldau, 2 stops to Karlsplatz.
  • Equally convenient, but slower is by S-Bahn to Wien Mitte station. At Wien Mitte take the U4 in the direction of Hütteldorf, 2 stops to Karlsplatz.
  • More expensive and just as fast as the Railjet: The City Airport Train (CAT) also takes you to Wien Mitte station. From there it is another 2 stops with the U4 (direction Hütteldorf) to Karlsplatz.

Alternatively, at the airport you can take the shuttle bus (Vienna Airport Lines) to Morzinplatz/Schwedenplatz. From there, take the U1 subway in the direction of Oberlaa/Alaudagasse, 2 stops to Karlsplatz, or the U4 subway in the direction of Hütteldorf, 3 stops to Karlsplatz.

Trains and buses run every half hour for most of the day.

Vienna has two main train stations, Wien Meidling and Hauptbahnhof (Vienna Central Station).

  • At Wien Meidling station: Take the U6 subway (direction "Floridsdorf"), 2 stops to Längenfeldgasse. There, on the other side of the platform, take the U4 (direction "Heiligenstadt") to "Karlsplatz" (4 stops). At Karlsplatz take the escalators at the back of the train and leave the subway station at the exit "Wiedner Hauptstraße".
  • At Vienna Central Station: Take the subway U1 (direction "Leopoldau"), to "Karlsplatz" (2 stops). At Karlsplatz take the escalators to Karlsplatz in the middle of the train and leave the subway station at the exit "Wiedner Hauptstraße".

If you are traveling with heavy luggage from the south or west, we recommend that you get off the train already in Vienna Meidling and not at Vienna Central Station (the walk from the trains to the subway is much longer at the Central Station).

Driving in Vienna is no pleasure - the streets can be quite congested and the many one-way streets and parking bans confusing. Also note that you must always give way to streetcars, no matter which direction they cross your path from. If you are arriving by car, the easiest and cheapest way to get around is to park your car near one of the train stations outside Vienna or in a parking house at a subway station at the periphery and then take public transportation. Note that there is a fee for on-street parking in Vienna and parking time is limited to two hours during weekdays.

For the brave who want to defy Vienna's traffic and can afford the parking fees:

  • Coming from the west, follow the signs toward the center, which will take you along Hietzinger Kai, Schönbrunner Schloßstraße and Schönbrunner Straße to Rechte Wienzeile. At the end of Rechte Wienzeile turn sharp right into Operngasse. There, on the left side of the street (Operngasse is a one-way street there), after the next traffic light, you will find the underground parking garage directly under the Physics and Mathematics building ("TU Tiefgarage").
  • Coming from the south or east, take the A23 freeway and leave it at the "Landstraße" exit. Then follow Landstraßer Gürtel and Wiedner Gürtel until you reach Südtirolerplatz. Turn right into Favoritenstraße, at the end of which you get into the left lane and turn into Wiedner Hauptstraße. Follow the one-way arrows in the map below to reach Operngasse via Friedrichstraße, where you will find the underground car park under the green Physics and Mathematics Building ("TU Tiefgarage").

The underground parking under the physics and mathematics building ("TU Tiefgarage") is quite expensive (4.20 EUR per hour, 7.90 EUR per day, prices summer 2023). It is open 24 hours a day (the entrance door is closed at night, but opens automatically). The ticket machine accepts credit cards, 50-, 20-, 10- and 5-euro banknotes, and coins of 2, 1, 0.5, 0.2, 0.1 and 0.05 euros.

Our History

The Institute was founded in 1966 as the Institut für Experimentalphysik II at TU Wien and renamed the Institut für Allgemeine Physik in 1975. The first director of the institute was Prof. Franz Viehböck (1970 - 1987). From 1987 to November 2006 the institute was headed by Prof. Hannspeter Winter. In December 2006 Prof. Herbert Störi was appointed director of the IAP. On October 1, 2009, the IAP was renamed to "Institute of Applied Physics". Prof. Herbert Störi was director of the institute until the end of 2015. The current director of the institute is Prof. Friedrich Aumayr.

The IAP logo, based on an idea of the late Prof. Hannspeter Winter, contains the letters "i" (center), "a" (left) and "p" (right) and at the same time forms the Greek letter Φ (phi), which is often used as a symbol for physics.
